If I open a hyperledger fabric genesis.block, there are CA certificates in the block. What I do not understand is why a "Transport Layer Security" CA cert has to be in the genesis.block. Also note that in the documentation, it says that currently TLS CA certificates can not be revoked, which would be another reason NOT to include the TLS CA certs in the genesis.block.
If someone could shed some light on this I would appreciate it.
